It's the shoulder season in New England: warm days, cool nights and changing leaves. There's still time for an autumn adventure with a faint hint of summer. And for that, you can't beat coastal Maine, where the ocean views are crisp and clean and the seafood is as fresh as can be. Hitch a ride with us as we walk Ogunquit’s Marginal Way and stop for a lobster at Barnacle Billy’s; head to York to sample the goodies at the Tasting Room of Stonewall Kitchen; browse Bath’s downtown district; and visit nearby Sebasco Harbor Estates, as rustic as it’s always been.
